I've read that SARS-CoV-2 virus which causes COVID-19 disease can be tested with RT-qPCR. It seems a somewhat lengthy procedure.
Then it's unclear to me: how do they test the virus in drive-through clinics in Daegu, South Korea? Specifically, do they use RT-qPCR testing or is there a faster way to test the secretion for virus?
Because "drive-through" normally implies that procedure is done on the spot. (Or do they only collect the samples in drive-through fashion, but the results come in later?)
